Preferably, the bracket 10 may be a plastic element P which envelopes a metallic element M to form an integrated piece. The metallic element M is arranged in the front panel 11 and stretches along the frame of the bracket 10. The combination of the plastic and metallic elements P and M provides lighter yet strong structure together with thinner structural profile.

Preferably, please refer to FIGS. 1, 2, 3A and 3B. The front panel 11 further includes front panel frame 113 that defines a front panel window 112. The front panel window frame 113 has a pair of sliding rail 1131 disposed on a parallel pair of the edges of the front panel window frame 113. The latch clamps 22 slidably mounted on the sliding rails 1131, thus allowing the sliding latch 20 to slide along the front panel 11.

Preferably, the sliding latch 20 further includes a latch window portion 23 conforming to the front panel window 112. The latch window portion 23 is surrounded by a latch window frame 24. The latch fastening portion 21 may have a tab receiving recess 241 and at least one latch jaws 25. The tab receiving recess 241 is arranged on one edge of the latch window frame 24 and the latch jaw 25 projects toward the latch window portion 23 from the latch window frame 24. In the instant embodiment, two latch jaws 25 are formed on either side of the tab receiving recess 241 as a preferred example and the structure thereof is not limited thereto.

The pair of latch jaws 25 and the tab receiving recess 241 together receive and lock the handle fastening portion 31. Furthermore, the shape, size and number of the latch window portion 23 can vary. Please refer to FIG. 5 for another embodiment showing a different example of the sliding latch 20 in accordance with the instant disclosure. The difference between the examples in FIG. 1 and FIG. 5 arises from the latch window portion 23 which is smaller in the embodiment in FIG. 5 yet still with the tab receiving recess 241 and latch jaws 25. The fastening portion 21 in FIG. 5 is disposed in a different edge of the sliding latch 20 while serving the same function as well.

The following description is based on the embodiment in FIG. 1 yet the embodiment in FIG. 5 can sill be referenced regardless the difference of the latch fastening portion 21. The handle 30 further includes a handle window portion 33 with a handle window frame 34. The handle fastening portion 31 includes a T-shaped tab 311 stretching outwardly toward the latch fastening portion 21. However, the T-shaped tab 311 is a preferred example in the instant embodiment and the structure of the tab is not limited thereto.

Please refer to FIG. 3A in conjunction with 3B. When the handle 30 moves along a close direction F21 toward the sliding latch 20, the T-shaped tab 311 firstly passes through the opening of the latch window portion 23 superposing the front panel window 112. Meanwhile the handle window portion 33 superposes the plate and the

front panel windows

23, 112. Then, the sliding latch 20 move along the sliding rail 1131 via the latch clamps 22 toward a lock-up direction F11 to allow firm engagement between the T-shaped tab 311 and the latch fastening portion 21. In other words, the T-shaped tab 311 is received by the tab receiving recess 241 and further held by the latch jaws 25, therefore completing the locking. Specifically, referring to FIG. 6 which shows an enlarged view of an enlargement portion A of FIG. 3A, the T-shaped tab 311 includes a neck portion 3112, and a shoulder portion 3111 arranged at the free end of the tab. A width W of the neck portion 3112 spanning from a side of the neck portion 3112 configured to engage one of the latch jaws 25 to another side of the neck portion 3112 configured to engage the other latch jaw 25 is substantially equal to a distance between the latch jaws 25. A distance between the shoulder portion 3111 of the handle fastening portion 31 and the handle 30 is substantially equal to the thickness of the latch jaws 25 of the latch fastening portion 21. During engagement between the T-shaped tab 311 and the latch fastening portion 21, the latch jaws 25 of the latch fastening portion 21 grip the neck portion 3112 of the handle fastening portion 31, and the shoulder portion 3111 of the handle fastening portion 31 in conjunction with the handle 30 grips the latch jaws 25 of the latch fastening portion 21.

In contrast, when releasing the hard disk drive, the sliding latch 20 moves along the sliding rail 1131 toward a releasing direction F12 so the T-shaped tab 311 moves out of the tab receiving recess 241 and is released by the latch jaws 25. Hence, the handle 30 can be opened toward an open direction F22.

Please refer to FIGS. 1, 3A, 3B and 4A. The handle 30 has a pair of cover rails 301 which is substantially perpendicular to the handle 30, extends toward the front panel 11 and partially encloses the upper and lower edges thereof. The handle 30 further includes a handle pivot member 35 with a wing 351 tilting away from the front panel 11. One of the cover rails 301 has a protrusion 3011 and the protrusion 3011 and the wing 351 define an opening 36.

Preferably, the side plates 12 include a plurality of holes H. The holes H can be used for receiving bolts or being reserved holes. The bolt holes can firmly secure the hard disk drive to the side plates 12. The side plates 12 may include a light guide groove 13. The light guide groove 13 extends to the upper edge of the front panel 11 from the side plate 12. When the light guide groove 13 is arranged with a light guide (not shown in the figure), the light guide directs the hard disk drive status indicator to the front panel 11, thus showing the hard disk drive status without demounting the removable hard disk drive holder.

Preferably, a supportive strut 15 is disposed in between the side plates 12. The supportive strut 15 provides better structural support to the side plates 12 and the entire bracket 10. Especially when a hard disk drive is not attached to the hard disk drive, the supporting strut 15 effectively minimizes damages by external shocks. In addition, the supportive strut 15 helps the bracket 10 to retain a mounted hard disk drive. Besides, as shown in the FIGS. 1 and 5, the connection between the strut 15 and side plates 12 may vary according to the structure thereof and not limited thereto.

Please refer to FIGS. 4A, 4B and 4C illustrating a series of actions of the removable hard disk drive holder assembly. As shown in FIG. 4A, given that a hard disk drive (not shown in the figure) is installed on the removable hard disk drive holder and the removable hard disk drive holder is moving along an assembly direction F3 toward a chassis B1. Firstly, as shown in FIG. 4B, the handle 30 is pulled toward the open direction F22 and the removable hard disk drive holder is pushed toward the assembly direction F3. The protrusion 3011 rotates to allow the entry of the removable hard disk drive to the chassis B1.

Moreover, please refer to FIG. 4C, the wing 351 tilts away from the opening 36 to allow a wider opening. When locking the handle 30 toward a closing direction F21, a chassis wall B11 is received by the opening 36 and abuts the protrusion 3011 while the wing 351 does not contact the chassis wall B11. The protrusion 3011 retains the chassis wall B11 as the handle 30 is completely closed. When the plate 12 is pushed toward the lock-up direction F11, the latch fastening portion 21 further secures the handle 30 by latching the handle fastening portion 31 (as shown in FIG. 3A) so the handle 30 cannot be opened unless releasing the plate 12. Hence, the protrusion 3011 firmly engages the removable hard disk drive holder and the chassis B1.

Preferably, the side plates 12 further include at least one elastic grounding edge 14 so the removable hard disk drive holder can be tightly engaged with the chassis B1.

In summary, the removable hard disk drive holder satisfies being both structurally firm and light and the associated members are minimized to reduce production cost.
